MACHINE FOR IIIIAMING AND REPAIRING ROADS SPECIFICATION forming part ofLetters Patent No. 789,603, dated May 9, 1905.

Application filed September 1, 1904. Serial No. 223,024.

1'0 all who/It it pm/y concern:

Be' it known that I, S'runn'r E. Flmmmu, a citizen of the United States,residing at Barberl'on, in the county of Summit and State of Ohio, haveinvented a certain new and useful Improvement in Machines for Making andRepairing Roads, of which the following is a specification.

My invention relates to road-making and road-repairing machines of theclass in which the scraper-blade is arranged for l1 rizontal diagonaladjustment between the front and rear wheels of a suitable carriage orwheeled body-frame and supported so that it can be raised and loweredand also bodily shifted toward either side of the machine.

Objects of my invention are to provide simple and eiiicient means forbodily shifting the scraper-blade toward either side of the machine atwill and to provide a steady working and powerful shifting device.

In the accompanying drawings, Figure 1 shows in side elevation theprincipal portions of a road-making and road-repairing machine forwardof the rear wheels and includes a handsha'ft and gearing involved in myimproved mechanism for shifting the scraperblade. Fig. 2 is a top planview of Fig. I and includes my improved blade-shifting device. Fig. 3 isa section taken transversely through the body frame in rear of the bladeshifting device and principally shows the blade-shifting device andadjuncts in elevation. In this view the blade is omitted. Fig. i is adetail. principally re n'esentil'ig a longitudinal section through aportion of the rack-bar, carrier, and worm or pinion of theblade-shifting device, a portion of the worm or pinion shaft being shownin elevation. Fig. is a detail showing a section through a portion ofFig. 3 at the left side thereof on line 5, the portions of the tie-rod,pinionshaft, and rack-bar shown in said figure being in elevation. Fig.6 is a detail showing a section through a portion of the machine ondotted line 6 in Fig. 3. Fig. 7 is a section through a portion of Fig.3, shown at the right, on dotted. line 7, the portions of the tie-rod,rack-bar, and worm or pinion shaft which are illustrated being shown inelevation.

A indicates the body-frame, and B indicates the scraper-blade supportedfor adjustment and side swing or shift, as in Patent No. 759,620, datedMay 10, 1904;. The support (I for the scraper-bliule is connected withthe swinging draft-bar I), and a cross-bar E, Fig. 3, is arranged upon ablade-snpporting device C, as in said Patent No. $).f20.

The device for laterally shifting the scraperblade cormin'ises atransversely-arranged rack F, supported upon the body-frame of themachine, and a carrier (3, supported to traverse the rack-bar F andprovided with a pinion or worm wheel II, which engages the rack wherebywhen said worm-wheel is operated it will cause the carrier G to traversethe rack or cross bar, and thereby move toward one side or the other ofthe machine, according to the directions in which the worm-wheel isturned. The slide or carrier (Ir connects with a cross-bar E by a link1, Fig. 3, whereby the snpport for the scraper-blade will be shifted inaccordance with the direction in which the slide or carrier G is moved.As illustrated in the drawings, the rack F is secured to the cross-bar 2on the main frame, said cross-bar being adapted to form a track orguideway for the slide or carrier G, it being observed, however, thatthe rack is, in ef feet, a part of the bar 2 and that, broadlyconsidered, the device is merely a rack-bar having a line of teeth andalso a portion which serves as a guidcway for the slide or carrier Gr.It will be noted, however, that the rackteeth are oblique to the lengthof the rackbar, as illustrated in Fig. 3, so as to adapt the rack to thestyle of worm-wheel illustrated.

The wm'm-wheol II is arranged to rotate with and slide longitudinallyupon the rotary operating-sha'ft I, provided at one end with beveledgear 3. The opposite end of the shaft I can be joinedin an ysuitableway. The shaft I is preferably square and extended through a square holein the worm-wheel II, whereby the worm-wheel is keyed upon the shaft soas to rotate therewith and also slide thereon.

CARCOUPLINGI SPECIFICATION forming part of Letters Patent No. 789,60i,dated May 9, 1905.

Application filed January 31,1903. Serial No. 1&1327.

To all whom, it may concern:

Be it known that I, FRANK J. Glens, a citizen of the United States,residing at Tyrone, in the county of Blair and State of Pennsyl- Vania,have invented a new and useful Car- Coupling, of which the following isa specification.

The invention relates to improvements in car-couplings.

The object of the present invention is to improve the construction ofthat class of carcouplings having pivoted knuckles and to provide asimple and comparatively inexpensive one of great strength anddurability, capable of coupling automatically, and adapted to retain theknuckle in an open position to prevent the same from accidentallyclosing, whereby the knuckle will be maintained in proper position forautomatic coupling and will obviate the necessity of going between thecars or in front of a moving car to set the knuckle.

A further object of the invention is to provide a safety device whichwill prevent a drawhead from dropping to the track and wrecking orotherwise damaging the cars in rear of it should it become disconnectedfrom the draft mechanism of the car upon which it is mounted.

Another object of the invention is to provide a knuckle capable ofopening automatically when the locking-pin is raised and it is free tomove and to enable the means for actuating the knuckle in the openingmovement thereof to support the locking-pin in an elevated position forautomatic coupling.

The invention also has for its object to provide a car-coupling of thischaracter which will be adapted to couple with the ordinary pivotedknuckle car-coupling and which will be adapted also to be connected witha pin-andlink car-coupling.

A further object of the invention is to provide a car-coupling capableof effectively coupling on a curve when the d raw-bars and drawheads arearranged at an angle to each other and when it is impossible for theknuckles to close completely and to permit the knuckles to close fullywhen the car-couplings assume their normal position in alinement witheach other.

lVith these and other objects in view the invention consists in thenovel construction and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings, and particularly pointed outin the claims hereto appended, it being understood that changes in theform, proportion, and minor details of construction within the scope ofthe claims may be made without departing from the spirit or sacrificingany of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of a car-couplingconstructed in accordance with this invention. Fig. 2 is a plan view,partly in section, showing two drawheads coupled. Fig. 3 is a similarview illustrating the arrangement of the knuckles preparatory tocoupling. Fig. 4: is a horizontal sectional view illustrating thearrangement of the knuckles when the draw-heads are at an angle to eachother. Fig. 5 is a transverse sectional view illustrating thearrangement of the locking-pin and the spring when the knuckle isclosed. Fig. 6 is a similar view illustrating the manner of supportingthe lockingpin in an elevated position for automatic coupling. Fig. 7 isa horizontal sectional view illustrating a detachable draw-head adaptedto be bolted to a draw-bar without removing the latter from a car ordisconnecting it from the draft mechanism should a draw-headbecome'broken or otherwise inoperative. Fig. 8 is a detail view of theknuckle. Fig. 9 is a detail perspective view of the locking-pin.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

1 designates a draw-head which may either be formed integral with adraw-bar 2, as illustrated in Figs. 1 to 45, inclusive, or beconstructed separate from the draw-bar, as shown in Fig. 7, and when theparts are constructed separate the draw-head will be provided at itsback with an opening 3, and the parts will be detachably secured bybolts 4 or other suitable fastening devices to enable the d raw-head ineventof breakage to be readily detached to permit another draw-head tobe applied to the draw-bar without removing the latter from the car ordisconnecting it from the draft mechanism thereof. The d aw-head is pro-
